In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigour, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are.

Method for cultivating a Procypris merus-Carassius auratus auratus hybrid and method for farming Siniperca chuatsi

The invention relates to a method for cultivating a Procypris merus-Carassius auratus auratus hybrid and a method for farming Siniperca chuatsi; the first method comprises the steps of subjecting Procypris merus as a female parent and Carassius auratus auratus as a male parent to artificial spawning induction, then carrying out artificial fertilization to obtain fertilized eggs, and debonding andhatching the fertilized eggs to obtain the Procypris merus-Carassius auratus auratus hybrid. According to the invention, the Procypris merus-Carassius auratus auratus hybrid is creatively bred by taking Procypris merus as a female parent and Carassius auratus auratus as a male parent, and is used as a feed fish for culturing Siniperca chuatsi. The limits on large-scale cultivation of Siniperca chuatsi due to natural conditions of the middle and northern parts of China, feed fish cultivation seasons and other factors can be resolved; the methods are suitable for southern areas and northern areas of China, help ensure the marketing of Siniperca chuatsi products in cold seasons; the ratios of protein content, fat content, total essential amino acids to total nonessential amino acids in the products are high; the muscle quality of Siniperca chuatsi fed with the Procypris merus-Carassius auratus auratus hybrid is higher than that of Siniperca chuatsi fed with Carassius auratus auratus.

SSR (Simple Sequence Repeat) marker primer for black camellia hybrid identification and application

ActiveCN114150083AGood repeatabilityStrong specificityMicrobiological testing/measurementDNA/RNA fragmentationBiotechnologyGenetics

The invention relates to an SSR (Simple Sequence Repeat) marker primer for black camellia hybrid identification. The primer has a primer number SSR31, an upstream primer: 5 '-CAAGGCAGAGTAGGCTGAGG-3', a downstream primer: 5 '-AAAAGGAAGGGAAAGTCA-3', a repetitive unit: (AGC) 7 and a fragment size of 212-273; the primer number is SSR48, the upstream primer is 5 '-GTTGGAGGTTTTTCAGCCAC-3', the downstream primer is 5 '-ATTGAAAGTCGCTGCTTCGT-3', the repetitive unit is (CCG) 7, and the fragment size is 249 to 300; the primer number is SSR250, the upstream primer is 5 '-ACCTCAGCTTCCATAGA-3', the downstream primer is 5 '-ATCTTGACGGGCGTAACATA-3', the repetitive unit is (CCG) 5, and the size of the fragment is 261 to 315. The invention also discloses a method for detecting the content of the CCG in the sample. The SSR marker disclosed by the invention is good in repeatability and strong in specificity; the black camellia hybrid is effectively identified by using an SSR molecular marker technology, the relationship between the black camellia hybrid and parent heritable variation is defined, and rapid identification and early selection of the black camellia hybrid offspring are realized.
